[CHORE] Add links to project sign up forms

[AntGa]

Description

We forgot to add a link to the sign up form that's the issue ☠️

Acceptance Requirements

• Add a link to the sign up form.

Specifically, this is adding links to each event.

If anyone wants to take this up, we need a good proposed solution.

This is mine:

Proposed Solution

1. Add a new column in the Notion Projects page, storing a Google form link associated with each project
2. Every time we load a project, we check for the existence of this form. If it exists, then we add a button to the side saying 'sign up'

Optionally, we could have another column with a date saying what day the form is due
